Emec MAX5 - ORP (mV) Calibration

20
mV Calibration.
ORP calibration procedure involves one calibration point and it requires one buffer solution. Default buffer solution is
650mV.
This procedure assumes that instrument is correctly congured and a working ORP probe connected.
Otherwise unattended results may occurr.
Once into “Calibration mV” menu move wheel on “Calibration” then press wheel to enter into calibration submenu.
Prepare 650mV buffer solution and dip probe’s sensor on it. Wait until reading value is stable and according to buffer
solution value move wheel until it is the same on display (“mV default” eld). Default value is 650mV. To end procedure
move cursor on “OK” and press wheel to proceed to next step.
Note: buffer solution value may change if environment temperature it’s different than 20°C. Read solution’s label for more
information. According to this occurrence “mV Default” must be changed.
End procedure by moving cursor on “Exit” from “Calibration mV” main menu and press it. If an error occurred during ca-
libration procedure then the instrument will show an error message and will ask to proceed to a new calibration, cancel
current operation or restore default settings.
